Application filed January 12, 1914. Serial No. 811,704.

cannot be adulterated, and by which refilling of the bottle, after itscontents have been once discharged, will be prevented. The invention also seeks to provide a device for the stated purpose which may be readily applied to a bottle after the same has been filled, and when applied will be held firmly therein so that it cannot be withdrawn.

The invention is illustrated in the accompanying drawings, and consists in certain novel features, whichwill be hereinafter;

first fully described, and then more particularly pointed out in the appended claims.

In the drawings, Figure l is a sectional View of a bottle neck showing my improved device in elevation therein; Fig. 2 is an eni larged vertical section; Fig. 3 is a horizontal section taken on the line 33 of Fig. 2; and i Fig. 4 is a perspective view of the several parts of the device, showing the same separated but approximately in their proper relative positions.

As shown in the drawings, the bottle neck 1 has its inner walls converging downwardly from its mouth or extremity, as indicated at 2, to a point substantially in the plane of the external head 3, usually formed on bottle necks, and then diverging downwardly to the body of the bottle, as shown at 4. In carrying out my invention, I employ a stopper, partition or body 5, which is somewhat conical externally so that it may readil enter the bore of the bottle neck. This body, stopper or partition is provided centrally with a bore 6, which is flared both upwardly and downwardly, the upper flared portion forming a seat for the valve 7, as shown clearly in Fig. 2. The said body 5 is provided with an external shoulder 8 which forms a seat or support for the lower edge of a packing 9 which extends up to the upper end of the body and over the lower edge of a cap 10, as shown. This cap 10 is preferably a metallic disk 11, provided with perl the cap permanently in place.

forations 12 and having a depending rim or annular flange 13 in which are formed slots or other openings 14. The lower end or edge of this depending flange or rim fits around the upper end of the body 5, and may be riveted, screwed or otherwise fastened to the body so as to be rigidly secured thereto. It will be noted, upon reference to Figs. 1 and 2, that the upper portion of the packing 9 extends over the lower end of the cap so that leakage will be eflectually prevented, and release of the cap guarded against. In actual practice, I form this packing of a rubber band of sufiicient thickness to bind firmly between the bottle neck and the body 5 when the device is inserted in the bottle neck, and of such a degree of elasticity that when it is fitted upon the body 5, it will contract tightly around. the lower end of the cap and thereby aid in holding the same in place. In some small sizes of bottles the use of rivets, screws, or other fastening devices may be dispensed with, as the pressure exerted by the packing will suflice to hold Formed upon, or rigidly secured to, the lower end of the body or stopper 5 are a plurality of fingers 15 which, in the present illustration, are disposed in pairs, the members of the pairs being diametrically opposite each other, and the two pairs being disposed at a ri ht angle. These fingers 15 form guides to prevent twisting of the stopper when the same is being inserted in the bottle, so that it will be caused to seat firmly and evenly against the inner converging portions of the bottle neck, and they are held against collapse while passing into the bottle neck by braces 16, having notches 17 in their ends which engage the diametrically opposite fingers, and provided at their centers with openings 18 to accommodate the valve stem 19. The valve stem 19 is rigid with and depends from the valve 7 which is adapted to seat in the upper flared portion of the bore 6, and a packing 20 may be provided in said seat, if desired, so as to effectually guard against leakage when the bottle is only slightly tilted. The valve stem 19 passes downward through the guiding braces 16, and to the lower end of said stem is secured in any desired manner a weight 21.

The construction and arrangement of the several parts of my improved device being thus made known, it is thought that the manner of using the same will be readily undervalve-supporting body or stopper 5 will be caused to move somewhat have been withdrawn.

lower in the bottle neck so that the packing 9 will be compressed between the walls 2 and the body 5, and the device firmly secured in position. 7 I have found that this 1 operation so wedges the device in place that it cannot be withdrawn, and to remove it from the bottle it is necessary to break the bottle neck. 'VVhen the bottle is in an lipr right position, the weight 21 holds the valve 7 upon its seat and,.consequently,- prevents the entrance of other liquids into the bottle, .so that adulteration of its contents cannot be efiected, nor can another liquid be fed into the bottle after its original contents To discharge all or a portion of the'contents of the bottle, the bottle is tilted in the usual manner, and the liquid will then flow into the lower flared portion of the bore 6 and will move the valve away from its seat. The liquid will then, of course, flow around the valve and through the openings in the cap to escape I from the mouth of the bottle.

The device isobviously simple in its coni struction, and is composed of very few parts, which may be cheaply manufactured and readily assembled. .The cap 10 effectually prevents the insertion of a wire or other device for the purpose of holding the valve open, and thereby permitting the refilling of the bottle, and the fingers 15 are positively held against bending or breakage while the device is being inserted in the bottle. These fingers, moreover, by engaging the inner walls of the bottle neck in advance of the valve-supporting body, cause the said body to assume a position concentric to the neck :so that it will seat firmly and evenly at the lower extremities of the converging surfaces; The braces 16, which serve to prevent bending or collapse of the fingers 15,

also serve as guides for the'valve stem 19 to prevent the valve shifting in its seat and, consequently, the valve will always fit its seat firmly and closely. v 7

Having thus described theinvention, 'what is claimed as new is A device forthe purpose setforth comprising a valve-supporting body having a central bore, a valveseated'in the upper-end of said bore, a cap carried by-the upper end, of the body and extending over the valve spaced fingers depending etrom thefl lower end of the body, braces extending be;

tween the diametrically opposed fingers and having notchesin theirends fitting around the said fingers, and a valve stem depending from the valve and extending centrally through the said braces.1 In testimony whereof I in presence of two witnesses.
